The Winter Group Fitness schedules are right around the corner. As most of us bring our outdoor workouts indoors, it is important to remember to keep your water bottle handy. Our thirst mechanism is reduced in colder weather, however, our hydration requirements may increase, especially for those who take any heated formats such as Formula 94, Heated and Hot yoga. A simple way to calculate your daily water requirement is to take half your bodyweight and drink that number in ounces; a 200 lb person should have 100 ounces of water each day. For every caffeinated or alcoholic beverage add 8 more ounces to your total.
